Durable solid waste-based foam light soil and preparation method thereof
The invention provides durable solid waste-based foam light soil and a preparation method thereof, and the durable solid waste-based foam light soil is prepared from the following raw materials in parts by weight: 25-30 parts of alkaline solid waste, 30-40 parts of silicon-aluminum solid waste, 5-10 parts of sulfate solid waste, 0.1-0.3 part of a water reducing agent, 0.3-0.5 part of a composite foaming agent, 0.5-1.5 parts of an expanding agent, 0.5-1.5 parts of anti-cracking fiber, 2-3 parts of an anti-freezing agent and 35-60 parts of water. The composite foaming agent is formed by compounding alkyl sulfonate and polymerized sulfonate according to the mass ratio of 1: (0.3-0.5), and the polymerized sulfonate is formed by copolymerizing an alkenyl-containing sulfonate monomer and an unsaturated phenyl tertiary amine monomer according to the mass ratio of (5-8): 3. Polymeric sulfonate not only can form a tough and difficult-to-break bubble liquid film, but also can improve the concentration of calcium ions around foams, form dense and firm hole walls and improve the bearing capacity of the hole walls to frost heaving pressure due to the fact that tertiary amine groups on side groups of the polymeric sulfonate are beneficial to complexing calcium ions.
本发明提供了一种耐久性固废基泡沫轻质土及制备方法，包括如下重量份原料：碱性固废25‑30份、硅铝质固废30‑40份、硫酸盐固废5‑10份、减水剂0.1‑0.3份、复合发泡剂0.3‑0.5份、膨胀剂0.5‑1.5份、抗开裂纤维0.5‑1.5份、抗冻剂2‑3份、水35‑60份，复合发泡剂是烷基磺酸盐与聚合磺酸盐按质量比1:0.3‑0.5的复配，聚合磺酸盐通过含烯基磺酸盐单体与不饱苯基叔胺单体按质量比为5‑8:3共聚而成。聚合磺酸盐不仅能形成坚韧不易破裂的气泡液膜，还由于其侧基上的叔胺基有助于络合钙离子，可提高泡沫周围钙离子浓度，能形成质密结实的孔壁，提高孔壁对冻胀压力的承受能力。
